I hate the practice of haggling because it is based on an asymmetry in the knowledge of the sellers and buyers. Instead, I'd prefer that all past sales be visible in a publicly accessible database, so that you could just see how much other people have been paying for stuff. Selling at a different price than the one that is recorded should then be a grave offense, a form of fraud.
